Even as cities and urban spaces are getting more polluted, a new technology developed by researchers at the Indian Institute of Technology Madras (IIT Madras) can help keep city streets clean and also eliminate harmful airborne dust. 

The dust from the streets has been among the biggest contributors to air pollution in cities. Inhaling this dust, particularly fine particles called PM2.5, is known to lead to health problems ranging from asthma and cough to other lung diseases.
